first quantum semiconductor (IMAGE) Technische Universität Dresden Caption Illustration of the first quantum semiconductor device where the topological skin effect was achieved. The flow of electrons (blue circle) along the edge, ensures unmatched robustness despite material deformations or other external perturbations. This quantum semiconductor signifies a breakthrough in the development of tiny topological electronic devices.
